I noticed a discrepancy in US Population figures that I can’t quite explain:
- The # of births was** increasing from 1976-1990 and also 1997-2007** (let’s call them Early Millennials and Late Millennials):
You can also check this on Page 3 of this CDC PDF: https://www.cdc.gov/nchs/data/nvsr/nvsr67/nvsr67_01.pdf
- However, US Population Pyramids show the population **under 20 declining **as of 2015/2016/2017:
Why? The Early Millennials make an appearance in the population pyramid, but the Late Millennials do not. It’s as if there was no baby boom from 1997-2007, but we know that there was, based on the # of births above.
Any thoughts on this discrepancy?
